摘要

解析模型在压电变压器设计中得到了广泛的应用。在本文中，有限元分析(FEA)对PT设计的额外用处将被展示。通过有限元分析，不仅可以通过最大化能量传递来优化PT设计，还可以清除杂散模式(几何2D/3D效果)的工作频率范围。此外，FEA工具允许研究PT设计的其他有趣方面，如制造公差或固定层对PT性能的影响(这是一个关键的设计点)。提出了一种混合解析与数值设计方法。

Mixed analytical and numerical design method for piezoelectric transformers

Analytical models are widely used for piezoelectric transformers (PTs) design. In this paper, the additional usefulness of finite element analysis (FEA) for PT design will be shown. With FEA it is possible to optimize the PT design not only by maximizing the energy transference, but cleaning the working frequency range of spurious modes (geometrical 2D/3D effects). Besides, FEA tools allow studying other interesting aspects of the PT design such as the manufacturing tolerances or the influence of the fixing layer on the PT performance (which is a critical design point). A mixed analytical and numerical design method for PT is proposed.
